7 Claims. (Cl. 28-19) This invention relates to improvements in bobbin cleaning devices and has particular reference to the provision of a device for removing waste weft from bobbins which have been ejected from the shuttles of a weft replenishing loom.

One of the principal objects of the invention is to pro vide a simple, eflicient and positively functioning device for use with weft replenishing looms for removing the waste weft from each bobbin after it has been ejected from the shuttle and subsequent to the replacing thereof with a fresh bobbin in said shuttle. Another object is to provide a bobbin cleaner for removing waste weft from bobbins subsequent to their being ejected from the shuttles of automatically functioning weft replenishing looms and which is self-functioning in causing the waste weft to be displaced therefrom after the weft has been removed from the bobbin.

Another object is to provide a bobbin cleaning device of the above character embodying parts having a reciprocating movement with respect to each other for automatically causing the waste weft which it has removed from bobbins to be displaced therefrom during its continued operation.

Another object is to provide a device of the above character which will function in response to an operative part of the loom thereby requiring no additional motion imparting means.

Another object is to provide a device of the above character, so positioned on the loom that the combined function of the bobbin which is conventionally ejected from the shuttle when the lay of the loom is in its most forward position and the conventional subsequent reversed movement of the lay of the loom will automatically cause the free end of the weft on the ejected bobbin to be drawn over and positioned in proper operative relation with the device whereby the said device will remove the weft from the bobbin and simultaneously cause the waste weft to thereafter be automatically displaced from the device whereby the said device is enabled to function continuously to clean ejected bobbins.

Another object is to provide a bobbin receiver, having an adjustable deflecting plate and an adjustable shelflike member adapted to function cooperatively with the cleaning device for initially receiving the bobbin as it is ejected from the shuttle and for delaying and controlling its path of movement subsequent to said ejection whereby the following rearward movement of the lay of the loom will automatically cause the free end of the weft on said bobbin to be properly associated with the bobbin cleaning device, said receiver having a slot in a side wall thereof for thereafter permitting the bobbin to fall under the action of gravity into a suitable receptacle.

Other objects and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings, in which:

Referring more particularly to the drawings wherein like characters of reference designate like parts through out the several views, the device embodying the invention, as shown in Figs. 1 through 7, comprises a tubular bearing member 12 having a threaded end 13 threadedly connected with a threaded opening 14 in a bracket 15. The bracket is secured to the frame 16 of a loom by bolts or the like 17. The tubular bearing member 12 is circular in cross sectional shape, as shown in Fig. 3, and has rotatably mounted thereon a tubular member 18 of rectangular cross sectional shape. On diametrically opposed sides of the tubular member 18 there is rigidly attached channel members 19 and 20. The said channel members 19 and 20 are attached to the tubular member 18 as by soldering or brazing or through the use of rivets, screws or the like. The said tubular member 18 further has channel members 21 and 22 slidably supported on diametrically opposed sides thereof. Each of the channel members 19 through 22 have positioned therein and throughout the length thereof strips of card or napper cloth 23 which comprises a base of rubberized canvas 24 having anchored therein wirelike teeth 25 which are ground on a substantially 45 angle with respect to the longitudinal axis of the device and in the direction of rotary movement of the tubular member 18 during the operation of said device. The card or mapper cloth is secured inwardly of the respective channel members 19 through 22 by bars 26 which are extended throughout the length of the intermediate portions of said cloth and which are secured to the channel members by screws or the like 27. The channel members 21 and 22, as shown in Fig. 2, have their inner ends freely slidable beneath overlying plates 28. To provide for such sliding movement the plates are secured to spacing blocks 29 screws or the like 30. The channel members 21 and 22 are slightly inclined outwardly and inwardly with respect tothe retangular tubular member 18 by, meansof spacer members 31 which are positioned between the inner ends of said channel members and said rectangular tubular member. The spacer members are secured to said channel members by soldering, welding, or the like. The outer ends of the slidably supported channel members 21 and 22 are connected by a pin 32 to an endblocks 33 having an outwardly tapering end 34. The block 33 is rectangular in cross section and is. slidably supported within the outer end of the rectangular tubular member whereby said channel members 21 and22 will be free to slidably reciprocate on said rectangular'tubular member 18. The block 33 has a threaded opening 35 therein in which is connected the threaded end 36 of a rod 37. The rod 37. slidably extends through a tubular member 38 which is rotatably supported within the tubular bean ing member 12.. The outer end of the tubular member 38 extends through a perforated bearing block 39 which is anchored in said rectangular tubular. member 18 having a press fit therewith. The adjacent free end of the tubular member 38 has a left-hand thread 40 thereon adapted to threadedly receive a nut 41 also having a left-hand thread. The nut 41 lies between the bearing block 39. and a collar 42-which is attached to the rod 37 by a set screw or the like 43. Internally of the rectangular tubular member 18, adjacent the outer end thereof, there is secured another perforated bearing block 44 and through which the rod 37 extends. The perforated bearing block 44 is secured to the rectangular tubular member 18 by screws or the like 45. Intermediate the block 44 and end block 33 there is a washer 46 of cushioning. material such as leather, rubber, or the like.

Intermediate the collar 42 and the perforated bearing block 44- there is mounted on the shaft 37 a coil spring 47 having one of its ends engaging the collar 42 and its other end engaging the bearing block 44 and functioning to constantly urge the rod 37 in an inward direction as indicated by the arrow 48. The tubular member 38 has mounted on the inner end thereof a ratchet wheel 49 secured thereto by a set screw or the like St The ratchet wheel lies within the recessed side areas 51 and 52 of a pair of pulleys 53 and 54 which are mounted to freely rotate on the tubular member 38. The said pulleys 53 and 54 are held in proper relation with the ratchet wheel 4-9 by a collar 55 secured to the tubular member 38 by a set screw or the like 56.

Each of the pulleys S3 and 54 are provided internally of their respective recessed areas 51 and 52 with a pivotally supported pawl, such as shown at 57 in Fig. 6, and each of which is resiliently urged into engagement with the ratchet wheel 49 by a coil spring, such as shown at 58. The pulleys 53 and 54 are adapted to be respectively rotated alternately in reversed directions by a continuous belt 59. The belt, as shown in Figs. 1, 2, and 7, has a looped end 60 positioned in overlying relation with an idler pulley 61 attached to the lay leg 62 of the loom by a pivot pin or the like 62a. The belt 59 has an upper portion 63 which extends from the loop 60 over, downwardly and around the the pulley 54 and has a lower portion 64 which extends from the pulley 54 to aloop 65 fitted upwardly over a floating pulley 66 and thence has an upper portion 67 extending back, over, downwardly and around the pulley 53 to a lower portion 68 which extends back to and is joined with said looped portion 60 fitted about the pulley 61. The floating pulley 66 is connected by a relatively stiff coil spring 69 to a fixed portion 70 of the frame of the loom by a pin or the like 71. The belt 59 is so arranged that when the lay leg 62 of the loom moves forwardly or in the direction indicated by the arrow 72, the pulley 53 willberotated in a clockwise direction with its pawl, 57 being so, disposed; as to ride freely onthe'ratchet, wheel 49.\yl1ile;the pulley 54., will 4 be simultaneously rotated in an anti-clockwise direction with its pawl 57* being so disposed as to engage andr0- tate the ratchet wheel 49. This causes the tubular member 38 to be rotated in said anti-clockwise direction. The pawl 57 of the pulley 53, however, is so disposed as to ride freely over the teeth of. the ratchet 49 in said clockwise direction. However, when the lay of the loom is moved rearwardly or in a direction opposite to that indicated by the arrow 72, the pulley 53 will be moved in an anti-clockwise direction and the pulley 54 in a clockwise direction. This now causes the pawl 57 of the pulley 53 to engage and rotate the ratchet wheel 49,. in an anticlockwise direction and to, in turn, impart said rotary movement to the tubular member 38. The pawl 57 of the pulley 54, which is now rotating in a clockwise direction, will ride freely over the teeth of the ratchet wheel 49. This alternate reverse movement imparted to the pulleys during the weaving operation. therefore sucessively and intermittently imparts a rotary movement to the tubular member 38 in said anti-clockwise direction. By reason of the fact that the threaded connection of the tubular member 38 with the nut 41 is left-handed, the nut, which is normally drawn tight against the block 39, will cause the rectangular tube 18 and channel members carried thereby to be simultaneously rotated in said anticlockwisedirection, This rotation will cause the card or napper cloth to grip the weft 73 carried by theejected bobbin 74 and wind it on the cleaning device. This is brought about because the ejection of the bobbin from the shuttle takes placevwhen the lay of the loom and the shuttle box are in their most forward position and just prior, to the return of the lay rearwardly. This subsequentmovement of the lay of the loom rearwardly causes the free end of the weft 73 from the ejectedbobbin to be drawn over and into engaged relation with the bobbin cleaning device, as shown in Fig. l.

The rod 37 whichis slidably supported in the tubular member 38 has an end 76 which extends inwardly beyond the inner end of the tubular member 38 to engage a bell crank 77. The bell crank is pivotally supported at 78 on the bracket 15.. The bell crank '77, as shown in Fig. 7, has a portion 79 connected through aspriug 80 and flexible link 81' to the lay leg 62 of the loom. Rearward movement of the lay leg 62' will exert a pulling action on the link and spring and on the portion 79 of the bell crank and, in turn, cause the portion 79a thereof, rocking about the pivot. 78, to press the rod end 76 inwardly. This causes the. collar 42 to compress the coil spring 47 and simultaneously causes the end block 33, which is threadedly connectedwith said shaft 37, to move in a direction outwardly or opposite the direction indicated by the arrow 48; Due to the fact that the sliding channel meme bers 21 and 22 are connected by the pin 32 to the end block 33 and are slidably supported beneath the plates 28 the said channel portions will he slid in an outward direction relative to they fixed channel portions 19. and 20.

As the lay ofthe loom moves forwardly and rearwardly, the shaft 37 will, in turn, be reciprocated in the tubular member 38' and will thereby cause the slidably supported channel members 21 and.22 to be likewise reciprocated; with respect to the fixed members 19 and 20. This reciprocating action takes place as the said channel members are intermittently and progressively rotated in thepreviously described anti-clockwise direction, and while the weft is being wound on said channel members. The teethof the card or napper cloth in the reciprocating channel'members-ZI and 22, will cause said weft wound thereontogbcv intermittently moved in an outward direction with-respect-to, said fixed channel members 19 and 20 and the teeth of the card-or. napper cloth in the fixed channel members 1 9 and 20 will intermittently engage the weft, as itris;m oyed-ot ltwardly-, to retain saidwcft in said;.outward ly moyed positions. This intermittent gripping of;th e weftgbythe card or-nappercloth of the-.fixed hanne t sm s sa ubseq ent: o he u rd-mo emen thereof by the card or napper cloth of the slidable channel members 21 and 22 will permit said channel members 21 and 22 to move inwardly without carrying the weft therewith and will eventually force the weft wound thereon ofi of the said channel members into a suitable receptacle provided to receive said weft.

To increase this action the slidably supported channel members 21 and 22, as previously described, are tapered outwardly and inwardly from their inner ends toward their outer ends. The teeth of the card or napper cloth in said respective channel members as previously described are angled in a transverse and outward direction with respect to the longitudinal axes of said channel members, as shown in Pig. 5. This is accomplished by grinding the ends of the teeth of the card or napper cloth in said direction and increases their gripping action with the weft wound on said channel members. This further aids the teeth of the sliding channel members 21 and 22 to be moved inwardly without drawing the weft inwardly therewith and causes the teeth of the card or napper cloth in the fixed channel members to more positively hold the Weft in their intermittently advanced positions of movement in a direction outwardly of the bobbin cleaner.

To more positively insure the weft being drawn over and in proper engaging relation with the bobbin cleaner, as shown in Fig. 1, there is provided an adjustable deflector plate 83 positioned adjacent the bobbin cleaning device. This deflector plate, when the bobbin is displaced from the shuttle, delays the dropping action thereof and causes the bobbin to drop, under the action of gravity, into a pan 84 beneath the cleaning device and having an angled bottom 85. The pan is pivotally supported at 86 so that the angle of the bottom may be varied as desired. The plate 83 is, in turn, pivoted at 87 to the end of the pan 84 so that its angle may be varied as desired. This is to control the delaying action of the dropping of the bobbin and the time interval required for it to roll down the angled bottom 85.

There is provided at the lower end of the inclined bottom 85 a space or opening 88 between the plate 83 and said bottom 85 to allow the bobbin 74 to eventually drop into a suitable receptacle 89 provided beneath said pan 84. Directly after the bobbin has been ejected from the shuttle, and during the following movement of the bobbin '74 as results from the deflector plate 83 and the inclined bottom 85, continued movement of the lay of the loom in a rearward direction will cause the end of the weft 73 to be brought over and into engagement with the bobbin cleaner. The plate 83 is retained in adjusted position through the provision of a link 90 pivotally connected at 91 to said plate and having a longitudinal slot 92 therein. A bolt carried by a fixed portion on the loom frame and having a wing nut 93 thereon is extended through the slot to lock the plate in adjusted position. By loosening the wing nut 93 the link may be adjusted relative to the bolt to angle the plate inwardly or outwardly, as shown by the arrow 94. The pan 84 also has a slotted link 95 carried thereby. The link 95 has a longitudinal slot 96 through which a bolt having a Wing nut 97 thereon is extended. The bolt is carried by a fixed portion on the frame of the loom and by loosening the wing nut 97 and the wing nut 93 the angle of the bottom of the pan 85 may be varied by swinging the pan on its pivot 86. Following this adjustment the proper angle of the plate 83 is set as described above. The pivot 86 is also carried by a fixed portion on the frame of the loom. By tightening the wing nuts 93 and 97 the deflector plate and bottom of the pan may be retained in adjusted position.

It is to be kept in mind that the bobbin cleaning device is intermittently rotated as well as having its slidably supported channels oscillated or reciprocated during the movement of the lay of the loom and thereby causes the weft to be drawn from the bobbin, wound on the cleaner and thereafter displaced from said cleaner automatically and in progressive sequence.

In Figs. 8 and 9 there is shown a modified form 'of the invention wherein a coil spring 98 is positioned internally of the rectangular shaped tubular member 18' which is similar to the rectangular tubular member 18 of the device illustrated in Figs. 1 through 7. The device of Fig. 8 is identical with the device of Figs. 1 through 7 and operates in a similar manner with the exception that one end of the coil spring 98 engages the inner end of the tubular member 38' having a left-handed nut 41 thereon and the opposite end of said spring engages the inner end of the block 33'. This normally causes the and block to be forced in an outward direction or in a direction opposite that illustrated by the arrow 48. In this instance, however, as shown in Fig. 9, the end portion 76 of the rod 37 is provided with a circumferentially grooved member 99 which is attaced to the said end 76 by a screw or the like 100. The arm 102 of a bell crank is provided with a bifurcated end straddling the member 99 and having diametrically opposed pins 101 fitting within the circumferential groove of said member 99 whereby the said member 99 may be rotated with the end portion 76'. The bell crank is pivoted at 103 to a bracket 104 similar to the bracket 15 and has an arm 105 connected with the coil spring 80 which is, in turn, connected with the lay leg 62 of the loom.

The belt and pulley arrangement, as illustrated by the belt 106 and pulleys 107 and 108 are similar to the belt and pulley arrangement illustrated in Fig. l and function in a similar manner. However, when the lay leg of the loom moves inwardly this causes the spring 80 to pull on the arm'105 and, in turn, causes the arm 102 to exert an outward pulling action on the shaft 37'. This causes the end plug 33 to be drawn inwardly to compress the spring 98 whereby the slidable channel members 21' and 22 are moved inwardly and, when the lay of the loom moves forwardly releasing its pulling action on the coil spring 80', the coil spring 98 will move the slidably supported channels 21 and 22' outwardly. The belt and pulley arrangement 106 through 108, which functions in a manner similar to the belt 59 and pulleys 53 and 54 of the device of Figs. 1 through 7 will cause the device to be intermittently rotated in an anti-clockwise direction to cause the weft to be wound thereon. The inward and outward movement of the slidably supported channels will cause the weft to be ejected from the cleaning device in a manner similar to the device of Figs. 1 through 7. As stated above the construction of the device of Figs. 8 and 9 is similar to that of the device illustrated throughout Figs. 1 through 7 except for the slight change set forth above.

In Figs. 10, l1, and 12, there is shown a further modification of cleaning device designated by the numeral 109 wherein the slidable channels 110 and 111 are connected with a rectangular tubular member 112 by screws, bolts, or the like 113. The said bolts 113, as shown in Fig. 11, extend through spaced longitudinally extending slots 114 formed in the opposed side walls of tubular member 112. The channel members 110 and 111, as well as the fixed channel members 115 and 116, have secured therein the card or napper cloth 117 in a manner similar to the previously described structures wherein bars 118 are extended throughout the length of the central areas of said card or napper cloth and are secured to the channel members by screws or the like 119. The bolts, screws or the like 113 also extend through said bars 118 which secure the card or napper cloth in the slidable channel members 110 and 111. The bracket 120, which simulates the bracket 15, in this instance is provided with a pair of inclined cam surfaces 121 and 122 which are adapted to engage suitable cam contacts 123 and 124 formed on the inner ends of the respective slidable channel members 110 and 111. When the said device 109 is rotated as may be accomplished through the use of a belt, pulley, and ratchet arrangement such as described in connection with the device of Figs. 1 and 2, or by a single pulley such as illustrated at 125, the pulley 125 is mounted on the end of a shaft 126 which rotatably supports the rectangular tubular meinber 112 in a bearing formed-in the bracket 120-. The cam surfaces Mind 122 are adapted to move the channel members 110 and 111 simultaneously in an outward direction and a coil spring 127 connected at one end 128 to the outermost bolt 113 and at its opposite end 129 to a pin 130 mounted in the rectangular tubular member 112 is adapted to move said channel members in the opposite direction. The cam surfaces 121 and 122 are so formed as'to'function cooperatively with the spring 127 to cause the slidably supported channel members 11s) and 111 to be'reciprocated during the rotation of the device.

The said device is otherwise so constructed as to function in a manner similar to the previously described devices. The pulley 125 may be connected by a belt 131 to a pulley 132 mounted on a shaft 135. The shaft 135 is mounted in the bearing of an adjustable bracket 133 attached to a fixed portion of the loom side 134. The said shaft 135 also has a pulley 136 mounted thereon. The pulley 136 is connected by a belt 137 to a pulley 138'mounted on the crank shaft 139 of the loom. The crank shaft 139 is a conventional part of the loom and through the belt and pulley arrangement described above imparts a continuous rotary movement to the bobbin cleaning device 109. In the end of the rectangular tubular member there is provided a tip 141 similar to the tips 33 and 33 of the devices illustrated in Figs. 8 and 2, respectively, to aid the device in displacing the waste weft after the weft has been removed from the ejected bobbin.

It is pointed out that the slidable channel members 21' and 22' of the device shown in Fig. 8 and the slidable channel members 110 and 111 of the device shown in Fig. are intended to be slightly inclined outwardly and inwardly with respect to each other in a manner similar to' and for the same purpose as the channel members 21 and 22 of Figs. 1 through 7.

In Figs. l3, l4 and there is shown a further modification of the invention wherein two channel-like members 142 and 143 are placed in base-to-base relation with each other as shown particularly in Fig. 15. One of said channel members 142 is attached to a bracket 144 by screws or the like 145. The bracket 144 has a sleeve 146 thereon rotatably supported within a bearing 147 carried by a bracket 14$, simulating the bracket 15, 104 or 129 of the previously described devices. The sleeve 146 has a pulley 149 secured thereto andwhich is con nected with a belt for rotating the same, such as the belt 131 of Figs. 10 and 12.

The channel member 143 is secured to a half-round section 151) of a shaft 151 rotatably mounted in the sleeve 146. The half-round section 150 is secured to the channel member 143 by brazing or the like or by the use of screws or similar means. Due to the fact that the shaft 151 is slidably supported in the sleeve 146, the adjacent ends of the channel members 142 and 143 are properly retained in aligned superimposed relation with each other. To retain the outer ends of the said channel members in proper aligned relation with each other, one of said channel members is provided with a longitudinal slot 152 in the base thereof through which is extended a screw 153 having an enlarged head overlying the slot 152 and its threaded end 154 threaded into the base of the other channel member 142, see Figs. 14 and 15. The said channel members are each provided with a pointed end portion 155 and 156 by tapering the side walls of said channel members 142 and 143 inwardly to meet each other as shown in Figs. 13 and l4. In addition to being formed pointed the respective outer surfaces are also tapered inwardly relative to each other as shown at 157 and 153. Internally of the respective channel members 142 and 143, like the previously described devices, there is provided strips of napper cloth 159 and 160'or. other similar material having fine wirelike teeth 163 thereon which are secured therein by barlike mem- 8 bers '161 and: 162 which extend longitudinally of said strips of napper'cloth or similar material. The barlike members 161 and 162 are secured to the respectivechannel members 142 and'143 by screws or the like-164; The

outer ends of said barlike members are turned slightly inwardly of the channel members beyond the outermost ends of the respective strips of napper cloth. Thewirelike teeth 163 are angled in a direction outwardly and are otherwise formed in a manner similar to the previously described teeth. a

The channel members 142 and pulley 149 similar to the pulley of 'Fig. 10 or by any of the belt and pulley arrangements previously described. This rotation of the channel members 142 and 143 is to accomplish the same results as the rotationof the previously described channel members. The shaft- 151 is provided with a circumferentially channeled disc 166 similar to the disc 99 of Fig.- 9. The disc is connected through the pins 167 to a yoke portion 168 of a bell crank 169 similar to the bell crank 77 or 102-of Figs. 7 and 9. A coil spring is positioned on the channel members 142 and 143. This causesthe channel 143 connected with the shaft 151 to be moved inwardly and outwardly relative to the channel 142. This movement results from having the portion 170 of the bell crank-1 169 connected with the lay leg of the loom in a manner similar to the connection of the portion 79 of the bell crank 77 of Fig. 7 to said lay leg. This isaccomplished through the use of a spring and link arrangement similar to the spring 80 and link 81 shown in Fig. 7 and which connects the bell crank 77 to the lay leg 62 of the loom. As the lay leg of the loom moves rearwardly, this will exert a pulling action onthelever '170 in the direction indicated by the arrow 171 whereby the bell crank 169 will rotate about its pivot 172 and cause the yoked end 168 to press the disc 166 and shaft 151 inwardly of the sleeve 146, thereby compressing the spring 165 and simultaneously moving the channel 143 and the napper cloth 163 therein outwardly with respect to the fixed channel member 142 and the napper cloth 163 therein. When the lay of the loom again moves forwardly releasing the pulling action of the lever portion 170, the spring 165 will move the section 143 inwardly relative to the section 142. This repeated action causes the section 143 to be'reciprocated relative to the section 142 whereby the waste weft wound thereon will be ejected from the device in a manner similar to the previously described devices.

It is particularly pointed out that the longitudinal axes of all of the above described channel members are disposed in a horizontal direction and are tilted slightly downward so that the outer ends of said channel members are lower than the inner endsthereof which aresnpported by the respective brackets. This functions to increase the ejection actionof the waste weft wound on said channel members during the reciprocation of the slidable channel member or members with respect to thefixed member or members. This function is also aided by inclining the reciprocating channel members as set forth in the previously described constructions.

The device illustrated in Figs. 13 through 15 is attached to the loom in a manner-similar to the previously described devices and is cooperatively related with the associated parts shown and described in connectionwith Fig. 1 in a manner similar to said previously described devices.

From the foregoing description it will be seen that simple and economical means have' been' provided for accomplishingall-ofthe objects and advantages of the invention. It will be apparent that rnanychanges may be 143 are rotated by the made in the details of construction and arrangement of parts shown and described without departing from the spirit of the invention as expressed in the accompanying claims. Therefore, it is to be understood that all matter set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

A device of the character described comprising a bracket, a bearing member supported in said bracket, means rotatably supported in said bearing member, a rectangular tubular member supported for rotation by said means in said bearing member, means having a plurality of teethlike members thereon fixedly supported on diametrically opposed sides of said rectangular tubular member throughout the major portion of the length thereof, means having a plurality of teethlike members thereon slidably supported on diametrically opposed sides of said rectangular tubular member and extending throughout the major portion of the length thereof, means for imparting a rotary movement to said ractangular tubular member and means for imparting a reciprocatory movement to said slidably supported means.

2. A device of the character described comprising a bracket having a bearing therein, means rotatably supported in said bearing, a tubular member mounted on said means to rotate therewith, said tubular member having rigidly attached on opposed sides thereof longitudinally extending strips of card or napper cloth having free ends and on the remaining opposed sides thereof slidably supported strips of card or napper cloth movable longitudinally with respect to said tubular member having free ends, means associated with said means rotatably supported in said bearing and with the respective slidably supported strips of card or napper cloth for causing said slidably supported strips of card or napper cloth to be reciprocated with respect to said rigidly attached strips of card or napper cloth with the free ends of said respective slidably supported and rigidly attached strips of said card or napper cloth being alternately moved outwardly beyond each other and for simultaneously rotating said I tubular member and said strips of card or napper cloth.

3. A device of the character described comprising a member having a bearing therein, means rotatably supported in said bearing, a tubular member mounted on said means to rotate therewith, said tubular member having rigidly attached on opposed sides thereof longitudinally extending strips of card or napper cloth having free ends and on the remaining opposed sides thereof longitudinally extending slidably supported strips of card or napper cloth having free ends, means associated with the respective slidably supported strips of card or napper cloth for causing said slidably supported strips to be reciprocated with respect to said rigidly attached strips with the free ends of said respective slidably supported and rigidly attached strips of said card or napper cloth being alternately moved outwardly beyond each other and means for rotating said strips of card or napper cloth.

4. A device of the character described comprising a bracket, a bearing member supported by said bracket, means rotatably supported in said bearing member, a rectan gular tubular member supported for rotation by said means rotatable in said bearing member, fixed channel like members on diametrically opposed sides of said rectangular tubular member, slidably supported channel members on diametrically opposed sides of said rectangular tubular member, card or napper cloth supported in each of said channel members and extending throughout the major portion of the length thereof, means for imparting a rotary movement to said rectangular tubular member and means for simultaneously imparting a reciprocagory movement to said slidably supported channel memers.

5. A device of the character described comprising a bracket, a relatively long bearing member carried by said bracket, a rectangular tubular member rotatably supported on said bearing, relatively long and narrow strips of card or napper cloth fixedly secured to diametrically opposed sides of said rectangular tubular member and extending throughout the major portion of the length thereof, relatively long and narrow strips of card or napper cloth slidably supported on diametrically opposed sides of said rectangular tubular member, a rotatably supported tubular member in said bearing member having its outer end operably connected with the rectangular tubular member, means on the inner end of said rotatably supoprted tubular member for imparting a rotary movement thereto in a given direction and a rod sildably supported in said rotatably supported tubular member, means for operably connecting said rod with said slidably supoprted strips of card or napper cloth, means for resiliently urging the outer end of said rod in an inward direction and means carried by said bracket for urging said rod in an outward direction and in opposition to said resilient means.

6. A device for removing waste weft from bobbins comprising rotatably supported relatively long and narrow strips of material each having free outer ends and closely related teethlike members thereon, said strips being disposed in back-to-back relation with each other with the teethlike members extending outwardly of the opposed sides thereof, and with their end portions disposed toward said free outer ends of said strips, means for imparting a longitudinal reciprocatory movement to at least one of said strips relative to another by an amount sufficient to cause the free ends thereof to alternately extend outwardly beyond each other, and means for simultaneously rotating said strips, said outwardly disposed portions of said teethlike members being adapted to cause the waste weft to be alternately drawn by one set of teeth outwardly of the other set as the reciprocatory movement takes place and to ultimately displace said Waste weft from the device by the extending of said free ends alternately outwardly beyond each other.

7. A device for removing waste weft from bobbins comprising rotatably supported relatively long and narrow strips of material each having closely related wirelike teeth members thereon, said strips being supported in back-toback relation with each other with the teethlike members extending outwardly of the opposed sides thereof, means for imparting a reciprocatory movement to at least one of said strips relative to another by an amount sufficient to cause the respective free ends of said strips to extend alternately outwardly beyond each other and means for simultaneously rotating said strips, said wirelike teeth members having their outer end portions angled outwardly toward the free ends of said strips and also slightly in the direction of rotation of said strips whereby the waste weft will wind on said strips by the rotary movement thereof and will simultaneously alternately be drawn by one set of teeth outwardly of the other set as the reciprocatory movement takes place and said alternate outward extending of the free end of one of said strips relative to the other causing said waste weft to be ultimately displaced from said strips.
